Cortana not showing the correct distance to a Place

[Vijay Kumar Kappa]

Cortana, when asked for distance to a particular place gives the wrong distance. Moreover, in the same screen it mentions 2 different distances. In the screenshot attached, for the same place it calculates 31km and 19.1 kms.

Maybe she shows what distance it would take for you to walk there and the displacement to that place.

That dosen't seem to be the case. The best route calculated with google maps is around 15 kms. Cortana is messing this up.
